2. Completely release the hand brake.
3. Unscrew the screw of fastening of a brake drum and remove a drum. The drum can badly act in film from a nave in connection with corrosion of a nave or because it is kept by brake shoes. In the first case for removal of a drum from a nave knock on drum perimeter with a plastic hammer or a wooden kiyanka. In the second case take a stopper from a viewing opening of a brake board and move the lever of the hand brake to a starting position therefore brake shoes will be taken away from a brake drum, and the brake drum should act in film easily.
